The Inner West Council is gearing up for a fight over a mammoth $1.3 billion apartment project, which could see a string of 20 buildings, including towers more than 100 metres tall and comprising 2600 units, built along a key road corridor.

Under a proposal by property giant Mirvac, a large section of Carrington Road in Marrickville would be rezoned for high-rise apartment towers up to 28 storeys, and would see existing business premises demolished to make way for the redevelopment.

Labor mayor Darcy Byrne slammed the proposal as "monstrous in scale" and on Thursday night the council voted to oppose the Mirvac proposal in its current form.

"The proponent seems to have confused south Marrickville with downtown Hong Kong," Cr Byrne said.

The proposed project would include 2616 residential units, as well as 17,300 square metres of new retail and commercial space.

To facilitate the development, Mirvac and the NVT Group, the landowner of the Carrington Road precinct, wants 7.8 hectares of the precinct to be rezoned to allow buildings up to 105 metres, as part of a plan to construct 20 buildings with heights ranging from two to 28 storeys.

The project would include 2616 residential units, as well as 17,300 square metres of new retail and commercial space.

A Mirvac spokeswoman said the tallest buildings under the proposal would be 28 storeys, but the council estimates that as many as 35 storeys could be built within a height limit of 105 metres.

The details of the project are contained in the planning proposal, which was submitted to the Inner West Council in May, are deemed "commercial in confidence" and have not been made public.

A planning proposal is an initial step in the planning process by which a developer submits an application to change the zoning or building restrictions on a parcel of land.

However, details of the proposal were revealed when a report containing the council's initial response to the plans was published ahead of Thursday's council meeting.

The report revealed council planning staff had written to Mirvac and the NVT Group last month, detailing a list of concerns and requested they provide further information before the proposal could be assessed.

Among the concerns relayed by the council was the prospect of mass job losses from the 148 existing businesses that operate along the Carrington Road precinct. The precinct is home to numerous creative industries and, according to council estimates, the precinct employs between 894 and 1440 full-time jobs.

The Council's planning department requested the developer "address in specific detail how these businesses and jobs will be accommodated in this urban renewal project".

In response to questions from Fairfax Media, a Mirvac spokeswoman said existing creative industries "will not be evicted" or displaced from the site during construction.

"Under the preliminary proposal the space dedicated to creative industrial and office users will be increased," she said.

"The small creative tenants will be accommodated in new, purpose-built light industrial creative space at a subsidised rent to ensure their continued presence in the precinct."

The council also took issue with scale of the project, describing it as an "unsuitable response to the site's context", and noted it exceeded the government's own recommended density for the Carrington Road precinct.

In the latest planning strategy for the Sydenham to Bankstown corridor, government planners identified the precinct as suitable for medium-high rise housing up to a maximum of 12 to 15 storeys.

A Mirvac spokeswoman said the redevelopment would feature 20 per cent publicly accessible open space, including a new park the size of two football fields.

It would also include the provision of affordable housing in line with the Greater Sydney Commission's proposed benchmark of 5 to 10 per cent.<!--EndFragment--><!--EndFragment-->
